Locations of all authoritative site addresses for Fairfax County. These addresses reside and are maintained in the Fairfax Master Address Repository (MAR) which is housed in the enterprise GIS database. This data contains not only the address, including street name, unit numbers for condominiums, city, state, and zip, but also several other related attributes such as jurisdiction and subdivision name that the address resides. This layer is updated daily from the data maintained in the MAR layer and related tables. Updates to this data occur when address data is recorded or approved and authorized by Land Development Service, Facilitation and Address Center (LDS-FAC).

Important information about unit numbers. This data is based on ownership and address site location. Therefore, addresses for apartment buildings will just have the primary building address. They will not include the unit numbers as there is no requirement for submission of unit numbers for apartment buildings in the county. Addresses for condominiums will have the primary address as well as the unit number as these are recorded with the Act of Condominium documents and each unit has separate ownership.
